Not sure about others, but, the last Moser 9" I installed on an 01' w/discs......

Make sure you have Moser machine the caliper adapters so you can get a wrench in to tighten the plates to the rr end housing end tubes. Something they forgot to mention to me. I ended up having a friend mill the plates for me. Then you can only use an combination wrench to a 1/4 turn at a time to tighten up the end plates with.

Just a FYI.
